Fixing Hotel Echoes Without Drilling Walls

from AcoustaPLOT Echo Hosted by AcoustaPLOT Echo

A listed Georgian hotel lobby and bar brought from 1.4s to 0.8s reverberation -- with every fix freestanding, since the stone and marble were protected. An illustrative worked example: a 12 x 9 x 4.5m combined lobby/bar (486m3) in a converted, listed Georgian townhouse -- stone, marble, plaster ceiling and sash windows, all hard surfaces, at 1.4 seconds reverberation with no statutory limit (target set by guest experience, roughly 0.7-0.9s). Listed status ruled out wall panels entirely, so every treatment was freestanding or removable: 22m2 of lined sash-window drapes, banquette seating for 14, and a 30m2 wool rug (the entrance marble left untouched). Result: 0.8 seconds.
